Write-Host"File deleted"-ForegroundColorGreen
Write-Host"Deleting files that are greater than 1000 mb"
$path="C:\vignesh\logs"
$allowedsize=1000
$fsize= (Get-ChildItem$path|Measure-Object-propertylength-sum)
$Sizeinmb="{0:N2}"-f ($fsize.sum /1MB) +"MB"
if ($Sizeinmb-ge$allowedsize) {
Get-ChildItem$path-Recurse|Remove-Item–Force
Write-Host"File deleted"-ForegroundColorGreen
